Patented Nov. 29, 1932 UNITED STATES PATENT OFFICE JOHN MCNUL'IY, OF CINCINNATI, OHIO, ASSIGNOR TO THE OHIO TRUSS COMPANY, A CORPORATION OF OHIO TRUSS Application filed May 29, 1931. Serial No. 540,849.

My invention relates to surgical trusses. The principal object of the present invention is to provide in a surgical truss means whereby parts which are apt to become soiled in use, may be readily replaced with clean and sanitary parts or may be properly renovated and replaced.

In the use of surgical trusses, the pad covering by reasons of body contacts, as well as the covering for the spring which fits around the body, rapidly become soiled and unsanitary. In order to overcome this difficulty my invention proposes to supply pad and spring coverings, which may be readily removed for renovation and replacementfor further use.

Further objects of the invention will appear from the following detailed description thereof.

In the drawings:

Figure 1 is a plan view of the inner plate of a truss pad constructed in accordance with this invention.

Figure 2 is a section of line 11 of Figure 1.

Figure 3 is a plan view of the outer plate of a truss in accordance with this invention.

Figure 4 is a section of a pad constructed in accordance with this invention.

Figure 5 is a view of the pad and cover assembly.

Figure 6 is a perspective of a portion of the spring cover and spring.

Figure 7 is a section of the spring end and shank assembly.

Figure 8 is a perspective of the complete spring and shank assembly.

In the construction of a truss pad in accordance with this invention, I employ an inner plate 1 constructed of metal of suitable rigidity. The plate 1 is of the general shape shown in Figure 1 andhas pins 2 secured near its ends, and a dished section 3 centrally located. Assembled in the dished section 3 of the plate is a spool 4. The pins 2 are provided with enlarged heads 10 and 11.

The plate 1 with its connections just described, is assembled in the pad in the usual manner familiar in the art. As so assembled the spool 4 and pins 22 extend rearwardly from the backof the pad. The numeral 5 indicates an outer plate having perforations to fit over the pins 2 2, and a central opening 12 to give access to spool 4. Pivotally mounted on the outer plate are lock plates 1313, each of said lock plates being provided with a notch 14 whereby the plate is' adapted to engage the shank of one of the pins 2 under the respective heads 10 and 11, thus securing the outer plate 5 in assembly with the inner plate and pad.

The numeral 15 indicates a fabric covering for the pad; said cover is providedwith eyelets around its edge through which a draw string 16' extends. The cover 15 is also pro vided with openings which are adapted to pass the pins 2-2. The cover 13 is placed over the pad and the draw string 16 tightened the ends thereof being wound around the spool 4 which secures same. The outer plate 5 is then placed over the pins 22, and the lock plates 13 closed around the pins so as to secure the parts in assembly.

The numeral 18 indicates the usual plate or bar secured by means of any suitably attachments indicated at 19 to the back of the pad. The numeral 20 indicates the usual truss spring to be secured to the free end 21 of the bar 18. A tubular fabric covering 22 for the spring 20 is adapted to slide freely over said spring. The end of the covering 22 is provided with a plate 23 having an open ended slot 24 to receive bolts 25 secured in the end of the truss spring. On the end of the bar 18 are pivotally mounted dogs 26-26 adapted to engage under the heads 27 on the bolts 25 to lock the spring in assembly with the bar 18. The end of the spring 20 is provided with a reenforcing plate 28 which serves in connection with the spring as securing means for permanently attaching the bolts 25.

From the foregoing description it will be seen that the fabric covering of the pad may be readily removed when it becomes soiled for renovation and replacement, or for replacement of a new covering when worn. The same is true of the fabric spring covering 22, which is also subject to soiling contact with the body of the wearer.

The truss constructed in accordance with my invention may be kept clean and sanitary at all times, and such contacting portions as may become worn from use may be readily replaced.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is.

1. In a truss, a pad comprising an inner plate, an outer plate, a removable fabric cover for said pad, draw-strings for tightening said cover on said pad, a countersunk spool on said inner plate for securing the ends of said drawstrings, and means for clamping the edges of said cover between said plates.

2. In a truss, in combination with a body spring, a removable fab ic cover for said spring, a pad arranged to be secured to said soring comprising an inner plate, an outer plate, a removable fabric cover for said pad, drawstrings for tightening said cover on said pad, a countersunk spool on said inner plate for securing the ends of said drawstrings, and means for clamping the edges of said cover between said plates.

.3. In a truss pad in combination with the truss pad proper and a fabric cover having drawstrings for securing said cover on said pad, apair of plates arranged to clamp the edge of said cover, a plurality of outwardly extending pins on said inner plate, a countersunk spool for securing the ends of said drawstrings on said inner plate, the outer plate having openings to receive said pins, and lock plates on said outer plate to secure together said inner and outer plates.

JOHN MoNULTY.
